HSS Step Drill Bits are perfect for drilling multiple-size holes in thin sections of metal&comma; plastic and wood using a single bit&period;

Each step drills does the work of many drill-bit sizes&period; Drills round holes in most metals &lpar;steel&comma; brass&comma; aluminum&comma; copper&rpar; up to 1&sol;8" &lpar;3&period;2mm&rpar; thick as well as in plastic and wood&period;

No center punching or pilot hole drilling is required on most sizes&period; The bits are easy to keep sharp&comma; and the hole size is easily determined by the diameter markings that are permanently laser-etched in the flute area&period;

Advantages&colon;1&period; No Centering required&comma; the drills do not run off center&period;2&period; A variety of hole diameters can be drilled using only one tool&comma; and the tool can display the dimensions&period;3&period; The dimension of drilled hole is exact&period;4&period; Holes are de-burred by the following level&comma; and cylindrical bores are produced&period;5&period; Even very thin-walled materials can be drilled&period;
